Disclosed is a lid-fastening structure for fastening a lid (66) using a bolt (96). In the lid-fastening structure (13), the bolt (96) is rotatably held in the lid (66) for closing an adjustment opening (73). An insertion hole (101) for inserting the bolt (96) is formed in the lid (66). A portion of the circumferential edge of the insertion hole (101) is cut out in a way that allows the bolt (96) to slide, and a backslide-limiting opening (104) for limiting the return of the bolt (96) to the insertion hole (101) is formed so as to be continuous with the circumferential edge. A supporting/fastening hole (108) is formed continuous with the backslide-limiting opening (104) to a smaller radius than is the insertion hole, the supporting/fastening hole being cut out so as to allow the bolt (96) to advance. |
